BAIL-MAKING MACHINE,

SPECIFICATION forming part of Letters Patent N 0. 788,817, dated May 2,1905- Application filed June 17, 1903. Serial No. 161,766.

To all 1071,0711, it may concern:

Beit known that I, O'rro S. BEYER, a citizen of the United States ofAmerica, and a resident of East Rutherford, county of Bergen, and Stateof New Jersey, have invented certain new and useful Improvements inBail-Making Machines, of which the following is a specification.

My invention relates generally to wirebending machines, and has moreparticularly reference to bail-making machines.

The object of my invention is the production of a machine which willautomatically and efficiently form bails for pails, kettles, &c. ,withinwardly-turned end hooks, the present case being a sister applicationto one filed by me on the 2d day of January, 1903, Serial No. 137,440.

I shall describe a machine of this character embodying myinvention andafterward point out the novel features in the claims.

The wire-bending mechanism consists, essentially, of a passive and anactive wire-bend ing member. These members are made in various forms,depending upon, the kind of bail desired, and are provided withauxiliaries in order to obtain the proper effect. The passivewire-bending member is conveniently in the form of a die-block of asuitable contour, normally stationary, but capable of a movement withthe active wire-bending memher to effect the proper operation. Theactive wire-bending member is conveniently in the form of two pivotedjaws of a contour corresponding to the die-block and adapted to claspthe same to effect the proper bending of the wire. The jaws are made toclasp the dieblock by means of two adjustable rolls usually mounted onthe framework. while the two jaws are brought into operating position bymeans of a slider moving in the bed of the machine.

The wire-feeding mechanism may be of any suitable construction and isinthe present instance substantially the same as the one shown in theapplication previously referred to.

My invention further consists in the general arrangement and combinationof parts and features of construction, as will more fully hereinafterappear.

In the drawings I have embodied my invention in a suitable form; butchanges in construction may of course be made without departing from thespirit of my invention.

In the said drawings, Figure 1 is a plan view of a machine embodying myinvention. Fig. 2 is a broken sectional view on the line m :1: ofFig. 1. Figs. 3, 4:, and 5 are detail views of the wire-bendingmechanism, illustrating the different steps in the operation of bendinga bail. Fig. 6 shows the bail produced by this form of bendingmechanism. Figs. 7 and 8 show a modified form of wirebending mechanism.Fig. 9 shows still another modification.

Similar letters of reference indicate corresponding parts in thedifferent views.

A indicates a bed or framework of any suit able construction supportingthe various parts of the machine.

Bis the wire-feeding mechanism, and D the wire-bending mechanism.

Power is derived from the shaft A, mounted transversely of the machineand carrying the pulley a and pinion a, the latter meshing with thespur-gear a on the main cam-shaft 'A, extending parallel with the shaftA. A is an auxiliary cam-shaft operated from the shaft A through thetrain of gears a", a and a.

The wire-feeding mechanism is in this instance of the conventional typeand consists of the usual two feed-rollers I), (one of which only isseen,) operated conveniently from the main shaft A by means of the crankt rack Z1 pinion b, bevel-gears If and I), and the usual ratchetmechanism incloscd in the casing 12 to impart an intermittentprogressive motion in one direction only to the said feedrolls in awell-known manner.

On either side of the bracket (0 are two sta tionary guides 0,preferably comprising pendent arms having perpendicular slots 0 open atthe lower end, or they may be described as bifurcated pendent arms.

Mounted on the rock-shaft 0 are two arms 0, having-slots 0 open at theends, constituting movable guides for the wire. These arms are locatedalmost at right angles to the stationary guides 0 and on the outer sideof the said guides. These arms are normally held in an upper position bymeans of the spring 0 attached to the framework and to the arm 0 of therock-shaft 0 When in this position, they intersect the stationary guidesat a point in alinement with the feed-path of the wire-feedingmechanism. The rock-shaft 0 is operated from the cam 0 on the shaft A bymeans of the roller 0 and lever 0 b is a cutting device for thewire-feeding mechanism of a well-known construction, operated by meansof the cam b on the shaft A roller 5 and lever I). This lever b ispivoted to the bracket I) by means of the bolt 6, while the bracket isadjustably mounted in a manner well known on the way I) by means ofbolts 6. hen the position of the bracket is changed, the cam b of coursealso has to be adjusted correspondingly on the shaft A A stop F islocated on the other side of the machine and at the end of the feedpathof the wire-feeding mechanism, against which the wire is fed. This stopis adjustable on the way o by means of the thumb-screw 6 and the holesZ). By adjusting this stop and the cutting device different lengths ofwire can be obtained. 6 indicates an arm centrally pivoted, as at 6 andadapted to pinch the wire between the head 6 and the face 6 during thecutting operation, it being operated from the cam 6 by means of therollo The bending mechanism consists primarily of a passive and anactive wire-bendingmember D and D Describing first the form shown in thegeneral views and in Figs. 3, 4, and 5, the passive member is composedof a die-block (Z substantially circular shaped and suitably mounted onthe bed.

(Z represents two recesses at the end opposite to the one adjacent tothe active wirebending member. The said die-block is,moreover, providedwith a rod (1 carrying a flange CZ, which bears against a compressiblerubber bumper (Z carried on the bracket 6 33 of the framework.

Ll is a bolt passing through the slot [Z of the die-block (Z 6Z denotesan auxiliary to the passive wirebending member, forming in this instancetwo fingers (Z attached upon the block (Z so as to have a slight playand located opposite to the recesses (Z of the die-block (Z The activewire-bending member is characterized by two pivoted forming-jaws d of acontour corresponding to the contour of the dieblook and mounted in thisinstance upon the slide (Z in the guideway 6Z8, formed in the bed orframework. The slide (Z is operated from the crank-pin (Z carried on thecrankshaft A the lever (Z forming a suitable connection between theslide and the crank-pin. On the framework on either side of the dieblockare located the rolls cl, adjustable by means of the hand-wheels (Z bymeans of which the jaws are caused to clasp the dieblook to bend thewire as they advance toward the same.

E is a stripping mechanism comprising an arm 6, mounted on therock-shaft e and carrying a transverse piece 6 extending over thedie-block, and provided with two strippers 6*, shaped to conform to thecontour of the said die-block. The rock-shaft e is operated from the came on the shaft A by means of the forked lever 6 carrying thefriction-roll e and connecting with the crank e on the shaft 6 Theoperation of the device is as follows: The movable guides 0 being intheir uppermost position, the wire-feeding mechanism is operated,feeding a strand of wire through the movable guides 0 and the stationaryguides 0, whereupon the arm 5 descends, pinching the wire while thecutting device 6 is operated, thereby severing the wire. The movable.guides 0 are now operated, carrying the strand of wire through the slot0 until the die-block is reached. The slide (Z now advances, carryingthe two forming-jaws (Z with it, which latter upon coming in contactwith the rolls (i are caused to clasp the wire against the die-block andaround the same, assuming the position shown in Fig. 4. \Vhile the wireis being bent around the dieblock and until the position shown in Fig. 4is assumed the said die-block remains stationary. Upon the furtherforward movement of the slide (Z the jaws having reached the end oftheir stroke,the die-block will move a distance with the said jaws, whenthe pressure becomes strong enough to overcome the tension of the rubberbumper. The effect of this is to move the die-block toward theauxiliary, the two fingers of which encounter the ends of the wire, soas to bend the same around the projections d forming the recesses (Z asshown in Fig. 5. Upon the retrograde movement the rubber bumper will ofcourse return the die-block to its normal position. The slide (Zthereupon recedes and the stripping mechanism B descends, removing thefinished bail from the die-block.

Numerous variations are of course possible, depending upon the kind ofbail desired. Thus, in Figs. 7 and 8, the end projections 42, carried bythe die-block, are shaped slightly different and located nearertogether, while the auxiliary in this instance consists of two formers(Z having jaws to engage the ICC projections d so as to bend the endhooks, which auxiliary is slightly movable with the said die-block bymeans of the pin (Z moving in the slot d on the block carrying theauxiliary. Again, in Fig. 9 the die-block is formed with squareincisions d at the end opposite to its auxiliary cl, the latterconsisting in this instance of a square block which bends the ends ofthe wire around the projections d. The style of bail produced by thebending members in this instance is of the style shown in Fig. 6 and ischaracterized by inwardly-turned end hooks.

Having thus described my invention, what I claim is 1. In a bail-makingmachine, the combination of a passive wire-bending member normallystationary and an active wire-bending member movable toward and awayfrom the passive member for bending a wire into bail shape, an auxiliaryfor forming the bail with in wardly-turning end hooks,and means wherebythe passive member is caused to move a distance with the activewire-bending member.
